Review on Binzzo Elastic Aluminum Extrusion Profile Hardware by William Hood

All M8 Nuts for 3030 rails are perfect. They have enough tension that they just won't fall through without a screw being screwed in and tightened, but they move slightly if you try to move them. I am very happy with them. BUT the M6 for 3030 rails were the complete opposite. Only one or two don't fall through the rail. And to top it off, I got 11 out of the 12 I ordered. They were just as disappointing as the M8.
